NATCO

National Fireproofing Corporation, also known as NATCO, was founded in 1889, in Pittsburgh, Pennsylvania. They re-branded from National fireproofing corporation, to NATCO in 1933. At their peak, they had 23 factories, including one in Haydenville, Ohio.

In 1933, NATCO changed their official company name from The National Fireproofing Corporation to The NATCO Corporation. Although NATCO manufactured the same products as The National Fireproofing Corporation, there were subtle changes when the company made the transition. The conduits were always called NATCO Conduits, but before the change they said “Manufactured by The National Fireproofing Corporation” after the change it became “Manufactured by The NATCO Corporation”. Since this change occurred in 1933, this information can be used to roughly date NATCO’s products.

Not sure if anyone can help but we have a huge lot (about 2000) pieces of NATCO bricks. There are all kinds from the conduit to the structural most in very good condition in light blue, mint green and a small amount of a light beige. They have never been used. We found these on a lot we were contacted to clear out and would like learn more about them and possibly sell them. I can’t post a photo here but am happy to send photos to anyone

We have an old milk house made out of NATCO bricks with white tile facing inside and out. The white tile has fallen off the face of bout 70 on the outside surface. Would like to replace if anyone has some
